Questions about part numbers and drive association for supported R740XD configuration

I am setting up 4 R740XD LFF chassis to be a VMWare ESA VSAN cluster each with 12 NVME drives and possibly use some SAS SSD drives as boot instead of BOSS.  (I'm just looking to utilize existing hardware for boot).

VMWare states in the ESA VSAN documentation that NVME drives must have direct connection instead of backplane.  After going over the cable routing documentation here I decided to go with  Figure 14. Cable routing – 24 x 2.5 inch drive backplane with 12 SAS plus 12 PCIe and adapter PERC over Figure 15. Cable routing – 24 x 2.5 inch NVMe drive backplane.

My questions are as follows;

1. I assume that figure 14 configuration will give the 12 direct lines to the 12 NVME drives to support direct NVME connection over figure 15.  Is that correct?
2. Figure 14 configuration are the drive slots specific to NVME and SAS - which drive slots are NVME and which are SAS?
3. What are the correct part numbers for the PCIE riser cards (are they the same or different) and what are the correct part numbers for the PCIE card to backplane cables?

4. If we want to add SAS drives along with it, must the adapter PERC card be a PCIE one or can it be a miniPERC?

5. If it must be a PCIE adapter, what is the correct part number adapter and for the cable?  (I'm assuming H330 Raid would be OK).
